Apple Bringing GeForce GTX 285 to Mac Pro
 
The GeForce GTX 285 Mac Edition will soon feature in Mac ProsMac Pro enthusiasts might soon have something to cheer about – Apple is bringing NVIDIA’s GeForce GTX 285 to its high-end Mac Pro systems. The new graphics card will signal the end of ATI Radeon HD 4870’s rule as the most powerful graphics card for the Mac Pro.
 
Widely considered to be NVIDIA’s fastest single-GPU, the Mac Edition of the GeForce GTX 285 will be manufactured for Apple by EVGA. The Mac Edition card features 1GB GDDR3 memory and 240 processor cores, and is identical in almost all aspects to the PC version including the dual-link DVI ports.
 
While clock speeds for the Mac Edition have not been revealed, NVIDIA claims that its performance will be at par with the GeForce GTX 285 PC edition. Apple plans on offering the new GPU to its customers as early as next month.

Hi guys i am back !!! I am very impressed with my new mobo !!! I will upload pictures tomorrow , right now all i had to do was use multiplier 9.0 x 440 to 3.96 ghz without changing any other values besides ram at 400 mhz x 2.00 d multiplier and i am stable overclocked at 3.96 ghz ( 4 ghz ) . Core temp reports the same temp i had even before oc :D 44 celcius lol how can that be ? i will use prime 95 now to stress and find out max temp . I l talk to you all later and upload images . :wavey:

plz let me know if these settings are okay , i had everything auto and i lowered vpu core myself to 1.3 ? maybe i can lower it a bit more and dont get a bsod , i think i can get it to 1.268 or something . Let me know if u need bios images too .



I also include some pictures of the whole day :D


HOW LONG DO I NEED TO RUN PRIME95 64 BIT ( MAX TEMP TEST ) TO TELL WHAT THE MAX TEMP IN MY CPU WILL BE ?

some more pics of settings and pc :D


Can you tell why cpu z doesnt show actual ghz in right hand side ? Maybe it will if i reboot but dont know why.It shows correct ghz and multiplier at bottom left side.Also vista control panel shows 4.18 ghz speed by the time it is 3.96.


Can someone tell me what tests to run to make sure i am okay ? How can i tell if nb is not getting pushed ? Plz try to be as specific as you can.First time O.C :D Thank you all

idle temp core temp 45 ( hot day ) . 98 % load torture max temp test 30 minutes went up to 63 celcius , how long should i run it to tell max temp ?

only voltages changed right now nb core from 1.1 to 1.2 , vcore from 1.225 to 1.3 and dram from 1.9 to 2.0 . No bsod are these acceptable settings for this oc ? 440 x 9 - 3.96 ghz 1:1 880 mhz

Looking good so far, temperatures seem acceptable. :)

Usually I run Prime95 for a minimum of 8 hours, not to find max temperature but to verify stability. Since your RAM is overclocked, it may be wise to run the blend test as it tests the ram more than the torture test.

Right now i dropped it to 3.8 with ram at 840 mhz , 1.28 v vcore 1,2 v nb and everything else in AUTO , its stable . If i go higher i will have programs crashing and thats because i dont know how to change all oc values and make them stable.I will get faster memory within the next week to do that

I will work on it later , if i use automatic O.C to get above that speed the values that gives them ex vcore 1.375 v seems too high to me , so unless i learn everything i keep it at this speed for now.


I used bios to O.C at 3.8 not ET6 , Thanks for your help

Excellent. Performed any further stability testing?

you dont need faster memory dude, just either up the memory volts or change the memory speed.

Also use print screen for screen shots.

Asfor your programs crashing that just means its unstable and needs more volts.

Dont forget volts = heat tho ;)

I run prime 95 64 bit for 8 hours , at core 1 i got a fatal error after 7 hours ( value expected to be less than 4 .... ? Value is 4.24653 ? ..... )


At core 2 i had no errors , what i did now i gave a bit more voltage to the cpu from 1.28 to 1.29 , having always nb at 1.2 and everything else AUTO


Hopefully that will fix that , i am also running memory 1:1 at 840 mhz

It's stable at 3.8 ghz (vista reports 4.02 ghz lol) , with vcore at 1.29 v , mch core at 1.2 v and memory at 840 mhz 1:1 :D , i m going to run 3dmark06 now to see what performance numbers i get and compare them to earlier ones.


I l try crysis at ultra performance so to make sure if its my video card that lags it and not my processor/ram. It plays well at max but lags on ultra high :D -- having AA above 8 if i remember ? :D


If i get no good benchmark results i l try to clock a bit higher and make it stable. C ya
